    Answer: Flow rate 1670 cm³/s

    Explanation:   Cross section  A =  π · (2 cm)²  = 12.56 cm²

                         V = 1000 l   , t = 10 min = 600 s

                           dV / dt = 1000 l / 600 s = 1,67 l/s = 1670 cm³ /s

                          That was not asked,

                       dV / dt = vA  and flow speed v = (dV/dt)/A = 133 cm/s
